      abstract     = {Close-packed monolayers of fullerenes on metallic
                      substrates are very rich systems with respect to their
                      rotational degrees of freedom and possible interactions with
                      different adsorption sites or next neighbours. In this
                      connection, we report in detail on the (2√3 ×
                      2√3)R30°-superstructure of C60 with respect to the
                      Au(111)-surface. We use molecular orbital imaging in
                      systematic UHV-STM studies to reveal the delicate balance of
                      interfacial and intermolecular interactions in this system.
                      Thus, bright C60-molecules in 5:6-top and 6:6-top geometries
                      are observed depending on the respective next neighbours.
                      Moreover, tiny changes in the appearance of the unoccupied
                      molecular orbitals of dim C60-molecules in hex-vac positions
                      are identified which are caused by the respective
                      interaction with the facets surrounding the Au-vacancy.},
